Na fabricação de pneus, o pneu vulcanizado ê submetido a outras fases de processamento, tais como a rebarbação e a medição. Gomo ê muito dispendioso estirar provisoriamente o pneu numa (jante, utilizam-se para dispositivo de sujeição as cbamadas jantes escalonadas. Gomo se trabalbam pneus com diâmetros de jantes diferentes, reproduzem-se minaw jante escalonada os ombros de varias dimensões de jantes. A jante escalonada é dividida em duas metadas, que se aproximam axialmente do pneu, dos dois lados.In the manufacture of tires, the vulcanized tire is subjected to other processing steps, such as deburring and measurement. As it is very costly to stretch the tire provisionally in a wheel, the wheels are staggered for handling the tires.While working with tires with different wheel diameters, the shoulders of various rim dimensions are reproduced. is divided into two halves, which approach the tire axially on both sides.

Podem tambám utilizar-se cubos oonsti-tuiàoe por vários segmentos susceptíveis de se deslocar radial mente. Estes segmentos são apertados uniformemente contra o talao do pneu, por meio de uma engrenagem. - 1 -Opposite hubs can also be used by various segments which are radially movable. These segments are tightened evenly against the bead of the tire by means of a gear. - 1 -

No caso das Jantes escalonadas utilizadas usualmente, há o perigo de que, devido forças de compressão mais elevadas aplicadas lateralmente, que devem provocar um forte assentamento do pneu, se deforme o pneu· Além disso, os pneus pequenos (por exemplo os de 35.56 cm (14")) são lateralmente cobertos pelos ombros das Jantes dos pneus maiores (por exemplo os de 40,64 cm (16w). Então uma preparação ou dimensionamento dos flancos laterais sá limitadamente ê possível· Os pneus tãm sempre de ser introduzidos na direcção radial na máquina de sujeição e posicionados com pre cisão entre as duas metadas da Jente· 0 cubo segmentado é, construtivamente, um dispositivo complicado, cuja fabricação e manutenção são dispendiosas. Nas fendas entre os segmentos podem acumular--se sujidades, que impedem o movimento preciso dos segmentos, 0 pneu fixado não i fechado de maneira estanque aos gases, de modo que, por exemplo quando da rebarbaçao, o azoto líquido usado pode atingir o interior do pneu, o que, no caso de quan tidades importantes, pode conduzir à destruição do pneu, devi do a corrosão e a tensões térmicas· A presente invenção tem por objecto um dispositivo para a fixação de um pneu, fácil de operar e simples de construir e no qual não aparecem os inconvenientes atrás referidos dos dispositivos conhecidos·In the case of staggered Rims usually used, there is a danger that, due to the higher compression forces applied laterally, which should cause a strong fit of the tire, the tire will deform. In addition, small tires (eg 35.56 cm (14 ")) are laterally covered by the shoulders of the rims of the larger tires (for example those of 40.64 cm (16w).) So a preparation or dimensioning of the side flanks is only possible · Tires always have to be inserted in the direction The segmented hub is constructively a complicated device, the manufacture and maintenance of which is costly. In the cracks between the segments, dirt can accumulate, which prevents the precise movement of the segments, the fixed tire is not closed in a gas-tight manner, such that, for example, during deburring, the liquid nitrogen used may In the event of significant amounts, it may lead to the destruction of the tire due to corrosion and thermal stresses. The present invention relates to a device for fastening a tire, which is easy to operate and simple to construct and in which the drawbacks mentioned above of known devices do not appear.

Segundo a presente invenção, o problema rssolve-se, montando axialmente, em relação ao pneu, um fole susceptível de ser inflado que, no estado de inflação, se encosta ao talões do penu·According to the present invention, the problem arises by axially mounting, relative to the tire, an inflated bellows which, in the state of inflation, abuts the lugs of the tire

Nas reivindicações secundárias indicam--se outras característioas da presente invenção. - 2 - I££ A presente invenção torna possível fixar o pneu rigidamente e centrado, sem que seja deformado. Através do ajuste forçado entre o talão do pneu e o fole podem transmitir-se forças elevadas ("binárias, forças axiais e forças radiais). 0 pneu não é descoberto na sua face exterior, de modo que não ae impede o tratamento. Além disso, o espaço interior ê fechado de maneira estanque aos gases. jOther features of the present invention are set forth in the secondary claims. The present invention makes it possible to secure the tire rigidly and centered without being deformed. Forced adjustment between the bead of the tire and the bellows can transmit high forces (" binary, axial forces & radial forces). The tire is not discovered on its outer face, so that it does not prevent it from being treated. In addition, the interior space is closed in a gas-tight manner. j

II

Num dispositivo de sujeição (2) em forma de tambor está fixado um fole de borracha (1) · Através de um veie oco (3) e de uma ligação (5) por um tubo flexível, pode transferir-se ar comprimido para o espaço intermédie en- i tre o fole (1) e o tambor (2). Desse modo o fole (1) fica inflado, até fazer pressão contra os talões (6) do pneu (4·) que o envolve, fixando o referido pneu. A operação de inflação centra o pneu no dispositivo. 0 valor da pressão interior determina a força com que o pneu assenta no fole (1). 0 pneu (4) não é deformado, mesmo para uma fixação rígida, visto apenas receber forças radiais nos talões, usualmente dotados de núcleos de aço. Pelo alívio da pressão, o fole (1) contrai--se de novo e pode retirar-se o pneu. Gom este dispositivo podem fixar-se pneus com pelo trés dimensões diferentes das jantes (por exemplo de 35»56 cm (14") a 40,64 cm (16"). - 3 -A rubber bellows (1) is fixed to a drum-like fastening device (2). By means of a hollow shaft (3) and a connection (5) by a flexible tube, compressed air can be transferred into the space between the bellows (1) and the drum (2). In this way, the bellows 1 is inflated until it presses against the beads 6 of the tire 4 'surrounding it, securing said tire. The inflation operation centers the tire on the device. The value of the internal pressure determines the force with which the tire rests on the bellows (1). The tire (4) is not deformed, even for a rigid fixation, since it only receives radial forces on the lugs, usually provided with steel cores. By releasing pressure, the bellows (1) will retract and the tire can be removed. By this device, tires may be secured with three different dimensions of the rims (for example from 35 "56 cm (14") to 40.64 cm (16 ").
